The Turkish National Movement (Turkish: Türk Ulusal Hareketi) encompasses the political and military activities of the Turkish revolutionaries that resulted in the creation and shaping of the modern Republic of Turkey, as a consequence of the defeat of the Ottoman Empire in World War I.

The movement was created through a series of agreements and conferences throughout Anatolia and Thrace. The process was aimed to unite independent movements around the country to build a common voice. The whole process is attributed to Mustafa Kemal Atatürk, as he was the primary spokesperson, public figure, and military leader of the movement.

The Amasya Agreement was important in many respects. It was the first call to the national movement against the occupying powers. It consisted of talks about national independence, based on provinces, not race. Even in this declaration we saw the roots of what constitutes the "Turk" as a political term, there was no distinction or reference to race or religion.[citation needed] The message read as follows:

The unity of the motherland and national independence are in danger.

The Istanbul government is unable to carry out its responsibilities.

It is only through the nation's effort and determination that national independence will be won.

It is necessary to establish a national committee, free from all external influences and control, that will review the national situation and make known to the world the peoples desires for justice.

It has been decided to hold immediately a National Congress in Sivas, the most secure place in Anatolia.

Three representatives from each province should be sent immediately to the Sivas Congress.

To be prepared for every eventuality, this subject should be kept a national secret.

There will be a congress for the Eastern Provinces on July 10. The delegation from the Erzurum Congress will depart to join to the general meeting in Sivas.

On American Mandate: On 1 August 1919, the King-Crane Commission tried to contact a large groups of interested parties in Constantinople (Ottoman Control), to obtain their positions with a view toward reporting them to the Paris Peace Conference. Kazım Karabekir learned that a memorandum was adopted by an amalgamation of political groups in Constantinople and consequently, the Erzurum Congress, which has been in session since 23 July (until 7 August 1919) sent a memorandum to American PresidentWoodrow Wilson on the same day (1 August). It was probably also meant to remind all other parties of Wilson's 14 Points and the fact that the Nationalists were aware of them. Among the objectives of the Nationalists was, it appears, to signal the resolve of the Nationalists to the interested parties, and display their intent not to tolerate indiscriminate political pressure. What began as a suggestion to the Nationalists to accept the American Mandate at the time of the Erzurum Congress, became a major campaign immediately afterwards. By the time Sivas Congress was convened, no less than three channels were working on the Nationalist leadership to persuade them at least to "consider" the American Mandate, if not outright adopt a resolution in favor of it at the Sivas Congress.

The Sivas Congress was the first time the fourteen leaders of the movement united under a single roof. These people formed a plan between 16 to 29 October. They agreed that the parliament should meet in Constantinople, even if it were obvious that this parliament could not function under the occupation. It was a great chance to build the base and legitimacy. They decided on formalizing a "Representative Committee" that would handle the distribution and implementation, which could easily be turned into a new government if allies decided to disband the whole Ottoman Governing structure. Mustafa Kemal established two concepts into this program: independence and integrity. Mustafa Kemal was setting the stage for conditions which would legitimize this organization and illegitimate the Ottoman parliament. These conditions were also mentioned in the Wilsonian rules.

Mustafa Kemal opened the National Congress at Sivas, with delegates from the entire nation taking part. The Erzurum resolutions were transformed into a national appeal, and the name of the organization changed to the Society to Defend the Rights and Interests of the Provinces of Anatolia and Rumeli. The Erzurum resolutions were reaffirmed with minor additions, these included new clauses such as article 3 which states that the formation of an independent Greece on the Aydın, Manisa, and Balıkesir fronts was unacceptable. The Sivas Congress essentially reinforced the stance taken at the Erzurum Congress. All these were performed while the Harbord Commission arrived in Constantinople.[1]

Plans were made to organize a new government and parliament in Ankara, and the sultan asked to accept its authority. A flood of supporters moved to Ankara just ahead of the Allied dragnets. Included among them were Halide Edip, her husband, Adnan Adıvar, İsmet İnönü, Kemal’s most important allies in the Ministry of War, and the last president of the Chamber of Deputies, Celaleddin Arif. The latter's desertion of the capital was of great significance. A legally elected president of the last representative Ottoman Parliament, he claimed that it had been dissolved illegally, in violation of the Constitution, enabling Kemal to assume full governmental powers for the Ankara regime.

On March 1920, he announced that the Turkish nation was establishing its own Parliament in Ankara under the name Grand National Assembly. Some 100 members of the Ottoman Parliament were able to escape the Allied roundup and joined 190 deputies elected around the country by the national resistance group. On April 23, 1920, the new Assembly gathered for the first time, making Mustafa Kemal its first president and İsmet Inonü, now deputy from Edirne, chief of the General Staff.

The national forces were united around the leadership of Mustafa Kemal Atatürk and the authority of the Grand National Assembly set up in Ankara, which pursued the Turkish War of Independence. The movement gathered around a progressively defined political ideology that is generally termed "Kemalism", or "Atatürkism". Its basic principles stress the Republic - a form of government representing the power of the electorate, secular administration (laïcité), nationalism, a mixed economy with state participation in many sectors (as opposed to state socialism), and national modernization.

Turkish revolutionaries were mainly influenced by ideas which flourished during the Tanzimat period. The revolutionaries should not be associated with the Young Turk movement of the same era, which was tightly bound to the Ottoman State and the ideals of Ottomanism. Turkish revolutionaries indeed were not a homogeneous group of people, as they had different ideas on social and political issues. There were years in which most of them did not communicate with each other, even though they presided over the major social and political institutions. The common idea which held them together was having a sovereign nation.
